10. AquaNotes

Ever notice how some of your best ideas appear when you're in the shower?
There are a lot of reasons for this
, but they're meaningless unless you have a way to remember those strokes of genius. Enter AquaNotes
, a waterproof notepad that you stick on your shower wall. It seems like a silly gimmick, but if you're a shower savant, you know it's much more than that. Heck, many of my best Lifehacker articles were conceived on this very notepad. Yes, I own one, and it's awesome. [$7.00 from AquaNotes, $7.75 on Amazon)

7. Onion Goggles

If cutting an onion brings on the waterworks no matter what you try, it's time for desperate measures.
We tested a bunch of methods
for avoiding onion tears, and found the best solutions came down to cutting the onion under a vent, or wearing these incredibly stylish and awesome goggles. Note: These work amazingly well for me, but Melanie found that the "one size fits all" size didn't fit her face at all. So, you might consider using swimming goggles instead. They're a bit less comfortable, but also cheaper and more likely to fit any face. [$19 on Amazon]

5. SleepPhones

It's hard to imagine something sillier than a music-playing headband you wear while you sleep, but
they exist
—and are quite popular. SleepPhones won't give you the highest quality audio in the world, but if you prefer to fall asleep to music, they're far more comfortable than normal headphones. Two Lifehacker writers actually own these and like them, and while they're a bit on the expensive side, they might be perfect for you. They also have a wireless version if you prefer. [$40 from SleepPhones, $40 on Amazon]

4. The Linux Cheat Shirt

You'd think
a shirt with a list of Linux commands would only be useful for impressing dates, but it's actually a solid cheat sheet for beginners. The text is upside-down, so you can read it while you wear it, and it contains basic commands, syntax, and even a guide to regular expressions. I've used it on more than one occasion, and it's better than printing out man pages. [$19 from the xkcd store]

Lego bricks are easily the most successful creativity-inspiring toys for kids. They're so…
